Identify the electrical activity associated with each of the ECG components and indicate whether the electrical activity in the heart has the same or opposite polarity as Lead II.
• P wave:
• QRS complex:
• T wave:
Homework Answers
Electrical activity associated with each of the ECG component is listed below:
1. P wave: Atrial depolarization(or depolarization of atria) is represented by P wave.
2. QRS complex: Ventricule depolarization is represented by QRS complex.
3. T wave: Ventricle repolarization is represented by T wave.
Electrical activity in heart has same polarity as LEAD II. LEAD II is very efficient and useful in detecting cardiac arrhythmias because it lie closely to the cardiac axis which is the same as the the overall direction of electrical movement allowing the best view of P and R waves.

Reading an ECG is a helpful skill to have for any medical professional. It gives tremendous insight into the various problems a heart is having and critical in diagnosing patients. Below you will find several ECG patterns the first one is a normal sinus rhythm. Identify which arrhythmia is represented by each of the remaining patterns and explain why. (It will be helpful in your explanation to refer to the P Wave, QRS complex, and T wave in your explanations.)...

Ms. J is a 78-year-old female client who presents into the clinic for her annual physical. When assessing her vital signs, her blood pressure is 160/92. 1. What could possibly be causing her blood pressure to be elevated? 2. Poorly controlled hypertension could eventually result in decreased cardiac output and heart failure. Why? 3. A routine electrocardiogram (ECG) is ordered. Explain the electrical activity of the heart and correlate the P wave, QRS complex, and T wave with the underlying...
